To the 0011211 46 isl'attached a shank 47, which carries the disk-like 90 head separator 48, which has a central opening; '49, having: an) eccentrically formed eattension 50 at oneside, belowwhich is ashel-f A 51, extending about one thirdof the distance around the central h-ole 49.

The tace thread 60 which is shown in Figs; 8 and 9, but, for clearness, not in. Figs. 1,2; t

and is threaded through the beads 61. 61

and is wound, with the beads loosely restin u on it one bead is upon it, on the reel 62, from which it is led down through the'trough 63, past the bead feeders 64, 65, which are reciprocated re spectively, through rod 66, attached to one arm of bell crank 67, the free end 68 of which rests against the eccentric 69 on the shaft 38, and through rod 70, attached to one arm 71, of a bell crank of which '72 is the hub, the other arm 73 of which bell crankbears against the opposite side of the eccentric 69, so that the feeders are rocked oncewith. each revolution of the shaft 33 to pass one head to the sprocket wheel 74. As this feeder mechanisniis the subject of a separate application, Serial Number 4459413, filed February 18t- 1921, I will not more particularlydescribe it. As for the purposes of this application I simply desire to indicate mechanism whereby the beads may be fed orward to the separator.

From the sprocket wheel 74 the thread passes down through the tube 53 to its foot 57, and through it and the separator 4-8 to the fabric, one bead being allowed to pass the separator with each revolution. of that element.

lVith each revolution of the driving sh aft. the needle 7 5 is reciprocated" once; one bead is passed by the bead feeders and allowed to fall down through the tube 53 to the separator 48 or to the top of the column of beads passed by the separator as it revolves, and is allowed to slide down the thread 6 to the; fabric, the eccentric inner dge of the separator cutting in between that bead and those above it, and preventing the latter from going on down; and, also, the thread 14 being thrown around the needle and around the thread 60, above the bead which has reached the fabric, so that, when the needle completes its stitch with the threadaathe stitch will attach and hold the thread 60 and its head securely to the fabric. I

Thedirection in which the fabric is fed is governed in the following way. A control shaft 7 6 is mounted in suitable hearings in the frame of the machine, and may be to tated by a hand crank 7 7 in either direction. Upon the shaft-76 are mounted sever: l spur gears 78, 79, 80 and 81 meshing, respectively. with spiral gears 82, on shaft 86, 83 on shaft 87, 84 on shaft 88, and 85 on shaft 89. each of which shafts is journalled in suitable hearings in the frame of the machine.

The shaft, 86, through crown gear 90, and crowngear 91 mounted on a sleeve 92, with-- in which the needle carrier is splined, rotates the needleca'rrier in either direction as desired; I v

The shaft "87, through crown gear 93, and crown gear 94- on the upper end of tube rotates that tube in either direction, causing crown gear 100, turns shaft rotation of the separator relative strung it to carry around with. it the foot 96 which is attached to the collar 97, fastened to tlnlower end of the tube by suitable means, such as set screws 98, 98.

The shaftSS, through crown gear 99, and 101, on which, mounted a collar 11? in hearings in which is pivoted a lever 103.

A cam 10? on the shaft 33, rocks a bell crank 10S, causing its aim 109 to press down a pin 110 on a bar 111 sliding in the head of the machine, the bar being raised again by a spring 112. The bar 111 carries a forked arm 113 in which the sleeve ll-l may revolve. in this sleeve loi'med a grooved seat 115, in which rests end 116 of lcvm- 112:3. which is pivoted in the collar 11? keyed on the shaft 101. The shank of this collar llT passes through an elongated. rectangular opening in a disc 118 mounted rotatahly in the extension 104 of the feeder bar 105.

The lower end of the lever 103 rests in a socket in the disc 11S, and springs 11: hold the disc and collar normally in the positi-iin;-- shown in Fig. 12. lVhen, therefore. the shaft 101 is rotated it carries around with it the collar 117, and when the sleeve .11 is pushed, down it will, through the lever 103 swing the disc, extension and feeder bar with the feed foot 106 in the proper direction to accomplish the desired feeding op eration.

The raising and lowering of the feederbar 105 is accomplished through hell crank 67 raising an arm 123 on a slide 124 in lllo head of the machine, which slide carries an arm 125 having a block 126 pivoted thereto and sliding on the tube 38, to which bloi-l-z the feeder bar is also pivoted. so as to he raised and lowered thereby. The slide. may be depressed by any suitable means. su h. for instance, as a spring 127.

The general features of this Feeding nu -h anism are understood by those acquainiwl with the prior art and they are simply shown herein to illustrate a type of operative mechanism to which my direction governing mechanism may be applied. 7

The shaft 89, through crown gear 120 and crown gear 121 on tube 53 turns that tube. and with it its foot 57, to the same cxtcin and in the same direction as the other two tubes and the needle are turned.

l n order, however, that the proper relation may be maintained between the separator in. foot 57, foot 90. the needle. and the direction of feed. it is requisite that the extent of he to the other elements shall be augmented or diminished to correspond with the extent of the forward or backward movement of the other cooper ating elements. That is the cycle of opera tion of the bead delivering and stitch form-- ing means, which may be called a stitch cycle, must be adjusted to correspond ac l l (l lv ll by a continuous y rotation of the curately with the angular change in the direction of iced.

lhis isaccomplished by securing upon the shalt 87 a gear wheel 122*013 halt the size oil and meshing with the gear 35. So that when the shaft 87 is turned, the yokeBt will be also turned, to one'half of the same exte E, but as the turnlng of the yoke 84L causes ts gear 31 to run ahead of or lag behind the gear 30, while the gear 32 is moved lorward or back an equal relative distance, the res .1

will be that the shaft 83 will be given an additional torwad movement equal to the forward movement of the 35, or its movement will be diminished to an cutout equal to the backward movement of the gear 35, the total movement being equalto that of shaft 87,

By these means I. secure a machine which, separator attaches the face or bead thread and beads securely to the tabric, which, as compared "with a one thread machine, is advantageous, because iione thread should break the sec ondthread will, to a large extent, hold the beads in place. ldesides, it permits of stringinp; the beads much. closer together upon the bead thread, as only suliicient space need be lei-t between the beadslfor their proper spacupon the "fabric andto permit of the around the head This is a decided locking; thread being cast thre c after each stitch. advantage in practice,

also the direction oil? the feed may be governed by a single controlling element, as the hand crank 77, so that the cooperating parts will all retain their proper relative posi tions and will function correctly as the teed is varied, there will be no irregularities in the work nor any interruptions nor complications in the operation of the machine.

l lhilc l have described the separator as passing one head at a time, it should be understood that it it is desired to pass more than one head at the same time that may be done, if the beads. are sutliciently short so that two or more will be passed together by the separator; or, the separator may be so proportioned as to normally pass more than one head; it being understood that at each a revolution the separator will pass a prede-.

tor-mined number of beads Whether one or more.

i wish it to be understood that details of my "lXIIIM'U'VBEDGDtS may be varied, as by the use of mechanical. equivalents or the like,

without departing from the spirit of my in v1 ion as described and claimed.
